I’d double that RAM, recently been working on larger projects and my 16GB can get eaten up if I’m not careful on what I’m loading into the cache
Also, I can vouch for the Phanteks Enthoo Pro ATX Case easy to clean the filters, nice cable management, I’ve had it sitting in plain view for a year now and I never get tired of staring into it’s soul >:D
I can’t comment on your choice of CPU but I’ve been using a i5 4690k (not over clocked) and have had no worries with UE4, photoshop, terrain software etc…
